SPRAY BOOTH.

Application filed December 3, 1923. Serial No. 678,104.

To a 107mm itjiitflfl/ concern:

Be it known that I, HOWARD G. BAn'riJNe, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a SprayBooth, of which the following is a specification.

This invention relates to improvements in spray booths and has for its object to provide a plurality of booths or cabinets in conjunction with a continuous track way, the alternate cabinets being reversed with respect to the intermediatecabinets to permit successive operators to work on opposite sides of articles to be sprayed. In the embodiment shown the exhaust from alternate booths is at one end thereof while the exhaust from intermediate cabinets is at the opposite end.

Another object. consists in the provision of an improved spray booth which is open at the sides and front and is provided with over-lying exhaust chambers at the top and rear with exhaust slots in the top and rear walls which slots may be varied in size and position to accommodate various conditions.

Another object consists in the provision of a removable slotted frame in the rear wall to permit access to the rear wall of the exhaust chamber for cleaning and other purposes.

Another object consists in the provision of a permanent exhaust or duct at the bottom of the rear wall projecting into the booth to create a circulation or exhaust draft beneath and at the rear of articles being sprayed.

These and other objects will be more fully set forth and described in the following specification and shown in the accompanying drawings in which Figure 1 is a plan view of an arrangement of spray booths or cabinets constructed according to my present invention, the top wall of the exhaust chamber being shown as removed from one cabinet and another cabinet shown in horizontal section.

Fig. 2 is a vertical section through one of the cabinets.

Fig. 3 is a perspective of the frame and e to the rear wall of the cabinet. 1

Like numerals refer to' like elements throughout the drawings, in which 10 designates, generally, a spray cabinet and booth having the corner posts 1O at each of the four corners and being open at the sides and front. A top wall 11 is provided and also a rear wall 12. Overlying the. top and rear of the cabinet is the exhaust chamber, generally indicated by numeral 13 having the outlet port or duct 13 for attachment to a main exhaust pipe 15 or for accommodation of an exhaust fan.

The exhaust chamber is formed by the wall 13" diverging from the top wall 11 of the cabinet at the .front thereof and the wall 13 diverging from the rear wall 12 of the cabinet at the bottom thereof, thus providing a gradually increasing top exhaust chamber 13 and an upwardly increasing exhaust chamber 13 at the rear thereof. Alternate of these booths when arranged in battery may be arranged for communication with exhaust pipe 15 While intermediate of the booths are arranged for communication with the opposed exhaust pipe 17, the intermediate booths being reversed in position, i. e., with the fronts thereof opposed to the fronts of the alternating cabinets. An endless trackway, generally indicated by numeral 20, extends through one of the booths to permit travel throughout of a track 21, or the like, upon which is mounted the article to be sprayed, indicated in Fig. 2 by numeral 22 representing in outline, an automobile body. The open sides of the cabinet 10 permit the passage therethrough of the article or object to be sprayed. Vith the arrangement shown in Fig. 1, for example, the operator in one cabinet may spray one side of the object, after which it is moved to the suceeeding cabinet and sprayed by an operator on the opposite side. For convenience I have located the booths with the rear Walls thereof adjacent the track way and with Tin exhaust or spray at the bottom to permit free movement and operation of the operator.

Extending between the angle bars 11 at the sides of the top wall 11 are the slats 25 removably secured by bolts 26'to the flanges of the angles 11 these slats being spaced to provide exhaust ports or ducts communicating with the exhaust chamber 13". The rear portion of.the to wall 11 is preferably solid in the embodiment shown, thereby enhancing the draft or exhaust action at the front of the cabinet where the operator is spraying, and where,.obviously, the fumes.

are created. These slats 25 may be removed, replaced by oth rs of different sizes, or relocated to vary the size or location of the exhaust slots 28 to correspondingly vary the exhaust or draft action to accord with the different conditions met with.

- flange inturned. Between the side angles extend slats 31 removably secured by bolts 31* to the side angles, these slats being spaced in the arrangement shown to form exhaust slots 32. Supporting pins 33project outwardly from the side angles whereby the frame 30 may be mounted upon the bracket 12, as shown in Fig. 2, controlling the exhaust through opening 12 through the slot 32. These slats 31 may be removed, replaced or varied similarly to the slats 25, described above, to vary the size and position of the ,slots 32. By this construction may be had control of the exhaust draft at the rear of the cabinet, preferably the lower portion thereof to remove such fumes, spray or the like which are not removed by the slots 28. The 'zapering of the exhaust chambers 13 and 13 permlts the maintenance of a substantially uniform draft effect at all of the slots. By positioning the draft slots or ducts at the front of the top wall and at the bottom of the rear wall, the draft cur-. rents tend to carry the fumes and paint or varnish particles away from the article to be sprayed, thus reducing or eliminating the deposit on portions of the article other than the surfaces being sprayed.

Below the draft opening 12 in the rear wall 12 is a transverse duct 36 in the bottom of the booth and extending across the rear thereof. This duct projects inwardly of the spray chamber to a point adjacent the trackway and assists in the creation of a draft beneath the article being sprayed and serves to remove the fumes or spray from the bottom of the cabinet. The'particles of coloring, varnish or the like, carried by the draft passing into chamber 13 impinge .upon the rear wall 13 and may be readily removed or cleaned off by removal of the frame 30 as will be obvious.

In use of the spray booth assuming a car body 22 would be passing therethrough, an operator will spray one side of the same in one booth, after which it will pass to the next booth and be sprayed on the opposite side by another operator. above the exhaust draft will remove the excess paint and fumes from the booth and the location and size of the draft slots may be varied as desired and as necessary.

As explained described, except as defined in the appended claims.
